product maintenance and installation instructions
1, the valve before installation, pipeline and valve should be cleaned, sealing surface is not zoned scar and dirt, to avoid leakage or reduce the service life of the product.
2, installation must check carefully clamp connection type is consistent, clamps and the valve connection should be the installation of special sealing ring, the valve and pipeline connection sealing is reliable. Horizontal pipe, vertical pipe can be installed.
3, the valve is installed into the pressure medium, the seal handle is rotated 90 ° check inside and outside, such as no leakage phenomenon, can be put into normal use.
4, used in the process such as the discovery of the valve is closed, still has leakage phenomenon, should replace the seals, re installed correctly, and then put into use.
5, the butterfly valve is generally used to connect and disconnect the media, can also be used to adjust flow, but not to the valve installed in the strict regulating media flow in the size of the.
